PT-C-DADM – Digital to Analogue Dolby/DTS Downmixer: Multiformat Audio Decoding for Stereo Integration
The PT-C-DADM Digital to Analogue Downmixer incorporates a 24-bit audio DSP to decode Dolby Digital (AC3), DTS, and PCM digital audio sources for stereo output in professional AV environments. Supporting both Toslink and coaxial digital inputs, this unit accommodates a wide range of source devices. Simultaneous RCA and 3.5mm analogue outputs enable integration with amplifiers, headphones, or distributed audio systems in meeting rooms, hospitality suites, control rooms, or high-end residential installations. Plug-and-play operation, combined with licensed multichannel decoding, streamlines deployment in hybrid and fixed AV setups.

• Multiformat Digital Audio Decoding: The integrated DSP decodes Dolby Digital (AC3), DTS, and PCM digital audio streams, converting them to stereo analogue output. This function ensures compatibility with a broad spectrum of professional and consumer audio sources commonly encountered in AV installations.

• Comprehensive Sample Rate Support: Full-spectrum PCM decoding is supported across 32KHz, 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz, and 192KHz sample frequencies. This capability maintains signal integrity and audio fidelity when interfacing with diverse playback devices or broadcast systems.

• Flexible Input and Output Options: Both Toslink (optical) and coaxial digital inputs are provided, with simultaneous analogue output available via RCA and 3.5mm connections. This flexibility enables straightforward adaptation to varied system topologies and device requirements in professional AV environments.

• Driverless Plug-and-Play Operation: The device operates without the need for external drivers or software configuration. This feature facilitates rapid deployment and minimises system complexity during installation or on-site troubleshooting.

• Licensed Multichannel Audio Support: Fully licensed decoding for Dolby Digital 5.1-channel and DTS-ES 6.1-channel streams ensures accurate downmixing to stereo. This compliance guarantees that no audio content is omitted when integrating multichannel sources into two-channel systems.

Reliable Stereo Integration for Professional AV Systems
By combining multiformat digital decoding, broad sample rate compatibility, and adaptable connectivity, the PT-C-DADM supports seamless integration of complex audio sources into stereo AV infrastructures. This unit provides a technically robust solution for environments requiring precise channel representation and reliable analogue output, addressing common challenges in meeting spaces, hospitality settings, and control room deployments.
